Application filed.

To all whom it may concerns Be it known that l, Wnn'rnn RUTH, citizen. of the United States, residing at Greensburglin the countyv of Kiowa and State of Kansas, ha e invented certain new and useful Improvements in Harrow Attachments, of which the following is a specification. a \v This invention relates to attachments for harrows like implements and adapted to cause the barrow to be momehtarily ele vated at the rear end to relieveits teeth of the accumulations of corn hobs, and other trash.

Another object of the invention is to provide a simply constructed device which. may be applied without material structural change to barrows oi: various forms and sizes.

With these and other objects inview the invention consists in certain novel features oi construction as hereinafter shown and,

described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention, Figure 1 is a plan view of a n a I a l tion or in engagement with the ground. Flg.

view similar to Fig. 2 showing the harrow in elevated position.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved device may be adapted without material structural change to harrows of various forms and sizes, and it is not desired therefore to limit the invention in this respect, but for the purpose of illustration is shown applied to a conventional barrow comprising a plurality of beams coupled by longitudinal members 11, each beam being provided with a plurality of harrow teeth 12 coupled to the beams by clips 13 of the usual construction. The terminal coupling members l1 are united by an 'evener member 14% to which the draft animals are connected, p

The improved device comprises a member adapted to be movabiy coupled to the harrow and operative by the torward movement of the barrow to elevate the rear end momentarily and thus permit accumulations of r utag" t .llidnif lllt dia 11 -1 1 *}38513, specification of letters Patent.

clods, corn hobs and other trash to escape. For the purpose of illustration the elevating member is in the form of a segment or half wheel represented as a whole at 15, mounted for rotation relative to the barrow, as for instance upon the rear beam 10. The meniber 15 may be of any suitable material and of any suitable size, but forthe purpose of illustration is shown with a rim 16, hub 17 and connecting spokes 18. The member 15 is likewise "formed of increased weight at one side, as indicated at 19, and preferably with a spur 20 at the weighted side, so that when released the member 15 will rotate an tomatically upon its center, as for instance upon the rear beam 10. Connected to the segmental. member 15 is a disk having a notch 22 in one side. Pivoted at 23 upon the barrow, preferably upon one of the connecting members 11, is a lever arm 2 1 adapted to engage in the notch 22 by its forward end, an d maintained yieldably in position as by a spring- 25. The member 15 will be located normally with its curved side upward as represented in Fig. 2, and to this end the notch 22 of the disk 21 is so located that'the lever arm 24 will engage the notch when themember 15 is in the position shown in Fig. 2 and thus maintain the member in that position against the tendency of the weight 19 to move the segmental member upon its center. By this arrangement so long as the barrow is operating under normal conditions the segmental member will remain inactive, or in the position shown in Figsv 1 and 2. When the harrow becomes clogged by clods or other trash, as above noted, the operator forces the rear end of the lever 2 downtaehes it from the notch 22 of the disk 21 wardly which elevates the forward end, dv

and thus releases the weighted side of the member 15 which immediately rotates upon its center and causes the spur 20 to engage the ground, and as the barrow moves forwardly the member 15 serves as a leverto cause the rear end of the harrow to be elevated into the position shown in Fig. 3, the member 15 rolling upon the ground until the terminal 26 of the segmental member is located downwardly, and as the harrow continues to move forwardly the fiat side of the segmental member will be moved into downward position and likewise move the weight ed portion 11 into position in advance of its center, and time cause the weighted portion to continue the rotation of the segmental member until the notch 22 is again in its upward p4 sition and will be automatically engaged by the shorter terminal of the member 24, thus automatically locking the member 15 in the position shown in Figs. 1 and 2. Thus to cause the operation of the device it'is only necessary for the operator to press downwardly upon the rear end of the lever 24 and then release the lever and when the member 15 is rotated into its former position it will be automatically locked ready for the next action.

The improveddevice is simple in construction, can be readily adapted to barrows of diflerent forms by slightly changing the form of the .bracket 27 which contains the pivot 23, but such slight changes do not constitute a departure from the principle of the invention, as the same results would be produced no matter in What shape the harrow may be constructed.

Having thus described the invention, what,

is claimed as new is: D l. The combination with a harrow includng a frame and toothed bars, of an elevatmg member-having a segmental rim and a solid Web at one side of the center to over balance the elevating member, a spur extending from the elevating member and coacting with the overbalancing web, and means for locking said elevating member in inoperative position relative to said frame and the toothed bars.
